I was an actual "trans kid", in that I "knew" I was a boy from a very young age, and transitioned much later as an adult. And yet...
They say the kid can give their assent - yes, but to what? In my case, if I'd been asked at age 11, I wouldn't have given my assent to go through the trial or not: I would simply have given my assent to whatever my mother wanted.
I trusted my mother and the adults around me to have my best interests at heart. I trusted that they knew better than me. So if they'd told me, "You should do it", I would have said yes, even if I'd been scared to death or reluctant for whatever reason. And if they'd said, "Don't do it," I would have refused to do it, no matter how desperately I might have wanted a chance to become more like a boy.
It would have had nothing to do with what I wanted to do - and everything to do with what the adults around me wanted me to do.
It breaks my mind that anyone who works with children can not be aware of that. And my heart is also breaking for the children who will be grossly abused during this trial. It's wrong, it's evil, and there's no excuse for it.
